At what age does child support end?

The age at which child support is ended is determined by the terms of the support order and nothing else. The order will either state "at the age of legal majority" or a specific age. It will also include the terms applicable to health insurance, education, and so forth. In some states it is necessary for the parent paying the support to have the order officially rescinded when the child reaches the designated age. Here is other input: * At the age of 18 or until they graduate from college. My uncle had to pay child support for his daughter and then at age 18 she wanted to go to college. He had to contiune with his child support payments until she finished college. She is almost a dr now. * Usually at age 18, unless you're agreement provide support if the child is a full time college student.
